Yup, certain most of the clicks made are invalid. better report it to Google before they misinterpret this incident. All the best

Hopefully. 62 clicks and 1 cent? Click bomb or attack on you. I would report it just incase. I would also check my logs to see if any ip activity look suspicious and take action.
A clear evidence of click bombing.... Report to adsense team as soon as possible to avoid a possible adsense ban. Check your log details and check from which IP you got this much clicks. Possibly it might be from single IP or a set of proxy IPs.
